Channel Emulation

3D channel emulation in a multi-probe setup

Introduction: As a solution to evaluate multiple input multiple output (MIMO) device performance in realistic conditions in the lab, MIMO over the air (OTA) testing has attracted huge interest from both industry and academia, see e.g. [1]. One promising candidate is the multi-probe based anechoic chamber method. Several papers have discussed OTA testing setups for MIMO devices with emphasis on ...

Environment Models for Realistic Simulation and Emulation of Wireless Networks

Wireless research and development requires effective and efficient simulation and emulation tools to validate and evaluate wireless designs. Wireless channel models are used in the tools to simulate signal propagation properties in the real physical world. However, due to practical issues, these models are often too generalized and simplified in large scale experiments, and they only provide li...

Potent Tree Codes and their applications: Coding for Interactive Communication, revisited

In this work, we study the fundamental problem of reliable interactive communication over a noisy channel. In a breakthrough sequence of papers published in 1992 and 1993 [Sch92, Sch93], Schulman gave non-constructive proofs of the existence of general methods to emulate any two-party interactive protocol such that: (1) the emulation protocol only takes a constantfactor longer than the original...

CAN Emulation in a Time-Triggered Environment

The Controller Area Network (CAN) protocol is a widely used event-triggered communication protocol, which o ers high average performance, exibility, and extensibility. However, time-triggered protocols are becoming more and more accepted as the communication infrastructure for safety-critical applications, since they support composability, dependability, and a deterministic behavior of all mess...
